Thanks a lot. Yes you will have to tweak it via VCDS. New HU will not have camera coding, so you will have to code it first otherwise camera will not work.

I have a Jetta Comfortline 2014 model, with factory fit front and rear parking sensors. My car has an RCD 320, will I require the quad lock connector, or any coding? asking because you've mentioned that its plug and play for the Jetta, but my car has the same unit as the Polo/Vento.

Can I just buy, install and forget? The reasons for upgrading are OPS Display, Better Bluetooth and I want to retain my steering wheel controls and the stick look.

Also, I have noticed that the RCD 330G variants are made by Harman, whereas the RCD 330 Plus just have VW branding, is there a difference in build quality and actual performance?

Might be irrelevant to this thread, but I think it is better to go for those DS-611 or the Android HU's. These got much better features and some of the the Android one's support wireless iPhone screen mirroring as well.

Not sure if it is the same model we are talking about here. Looks the same though.

Yes it's exactly same model. You can just buy No Name RCD from above link, buy 512 MB RAM and solder additional RAM to RCD, or just buy complete package with ready to use Apple CarPlay (it's costly though - around $200).
